Our first hatch and we have a very small incubator. Our temp has been great at 99.5 consistently and our humidity also. Our question is in the little giant incubator hydrometer it has electric cords with a plastic piece that lays on top of the eggs in the center. Do we leave this here during lockdown or hook it up off the eggs. We've had 2 pip and been awhile but still wiggling eggs and such. Today is day 21 actually tonight would be lol. Any advice?
